ATLANTA, GA--(Marketwire - June 13, 2007) - Scientific Atlanta, a Cisco company (NASDAQ: CSCO), today announced new, compact, high-density Prisma II™ optics
products designed to improve the performance of existing fiber. At the
upcoming SCTE Cable-Tec EXPO in Orlando, Fla. next week, June 20-22,
Scientific Atlanta will also offer a look at a new DOCSIS® Passive
Optical Network (D-PON) architecture to enable operators to deploy
cable-centric/cable-friendly fiber-to-the-home (FTTH) technology that does
not require the significant changes to network management necessary with
earlier FTTH cable architectures.

"In addition to providing the technology necessary to extract more capacity
and performance from existing fiber, these new Prisma II products will help
our customers reduce the rack space required in existing hubs or headends,"
said Mark Palazzo, vice president and general manager, Transport and Access
Networks for Scientific Atlanta.

The Scientific Atlanta® D-PON architecture provides a truly passive,
migratable solution to FTTH deployments for cable operators. The D-PON is
especially beneficial for operators who need to deliver FTTH service for
greenfield developments. Using a 32-way split PON infrastructure,
Scientific Atlanta enables cable operators to create an effective optical
budget in both directions. Downstream, the D-PON uses 1550nm technology to
provide cost-effective forward optics to get to the side of the home. For
the upstream traffic, technology developments at the optical network
terminal (ONT) location will provide a cost effective way to support very
long distances. This helps the operator avoid having to insert costly,
multiple actives into the network to amplify signals to compensate for any
loss.

"We see the D-PON architecture as a valuable and cost-effective solution
for cable operators as they respond to the fiber-to-the-premise
requirements that most residential and commercial developers are defining
for new planned communities and multi-use facilities," added Palazzo.

These technologies will be on display at the Cisco/Scientific Atlanta booth
865 at the upcoming SCTE Cable-Tec Expo 2007 in Orlando, Fla., June 20-22
in the West Hall at the Orange County Convention Center. To arrange an
